@Jason Lantz and @Dave Manelski - One of the things that escaped my notice in Winter 16 until I took the usual renewal exam appears to be the GA of editing Audit Fields via API with System Permissions. Previously, this was a request to Salesforce.com support. This means that using tools such as Data Loader and DemandTools, we can now import data with historical dates without having to jump through hoops, so, yay.
I'd toss this on GitHub, but thought it might make an interesting discussion here: What do you think of adding System Audit fields to the NPSP Data Importer for all it's Objects? This might require refining the tool a bit more, since if it truly becomes a proletarian item (as I'm personally hoping it might for power users - *cough* Custom Permissions Fix *cough*), not every User will have the ability to edit Audit fields. Also, I'm not sure how API availability relates to the Apex behind the tool, so I'm honestly not sure it's even possible.
Thought I'd ask and see what you and others thought. Good/useful? Evil/destructive? Somewhere in-between?
It's a known issue that this does not work anymore with NPSP Data Import functionality.

Until this can be addressed (again), you'll need to use another tool to import data and set the original created date. Sorry for the inconvenience.
